Bug reports of function square_abs

The function square_abs has only one-line code : y = square( cvx_linearize( x, ‘cabs’ ) );

typing square_abs(-2) in the MATLAB command window, it throws a error as follows:
Error using cvx_linearize (line 42)
Invalid mode: cabs

Error in square_abs (line 13)
y = square( cvx_linearize( x, ‘cabs’ ) );

After adapting the code as follows y = square( cvx_linearize( x, ‘abs’ ) ), it works.

MATLAB version: 9.0 (R2016a)
OS: Windows 7 amd64 version 6.1
Java version: 1.7.0_60
Verfying CVX directory contents: No missing files.

The latest version of square_abs change the codes to y = conj( x ) .* x;
Also add a error check procedure: error( nargchk( 1, 1, nargin ) );
However, nargchk will be removed in a future release. Use NARGINCHK instead.
Sooooo many warning happens when using the the latest version of CVX in MATLAB 2016a.

You should state the CVX version and build number, not just that it is “the latest version”.
